UNITED `lsTATils PATENT WILLIAM BURTON STEEN, OF MILLCREEK TOWNSHIP,ERIE COUNTY, PENNSYLVANIA.

HOSE-COUPLING.

Specification of Letters Patent.

Patented Sept; 8,1908.

Y v Application filed January 25, 1907. Serial No. 354,017.

To all whom it may concern:

Be it known that I, WILLIAM B. STEEN,

a citizen ofthe UnitedStates, residing in Millcreek township, in thecounty of Erie and State of Pennsylvania, have invented new and usefulImprovements in Hose- Couplings, of which the following is aspeciication.

This invention relates to hose couplings and consists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out in the claim.

The object of the invention is to make a quick acting hose couplingwhich when coupled, is looked in position; to make a more perfect jointwhen the couplings are together and provide means by which the couplingmay be readily unlocked and uncoupled.

The invention is illustrated in the accom- -members coupled. Fig. 7, atop view of the panner wrench for operating the coupling. ig. 8, a sideelevation of the same. Fig. 9, a large section of the locking pawl.

1 marks the male member of the coupling g 2 the female member. These areprovided with the corrugated surfaces 3 for facilitating the fasteningof the hose to the coupling. The male member has the shoulder 4 againstlwhich a gasket 5 is arranged. A tubular projection 6 is provided withthe cam lug 7 having the cam surface 8. There are preferably -two ofthese cam lugs 7 and each point of the cam surfaces 8 of the lugs 7 arein the same line, extending through the axis of the coupling and atright angles to' the axis. The female member has the socket 9` in whichthere are the inwardly extending lines 10 with the cam surfaces 11arranged to operate on the cam surfaces 8. By havingthe same axialarrangement ofthe cam surfaces 8 on both lugs 7 and a similararrangement on the lugs 10, the coupling can be made with either lug 10on either lug 7.

I prefer to supplement the joint formed fr with the gasket 5 which isbetween the shoulder and the male member on the end of land a-seat 13-on the male member. -can be brought into contactaf-terfthegasket -5 hasbeen somewhat-compressed.

the female mem-ber by a metallic joint. referably a conical joint. Thisis efecte making the seat 12 on the female-member These I provide a setof ratchet teeth 1.4 on one i member, as shown on the female memberandvon the other member, 'as shown in the male member, I arran e ratchetawl for operating on these teet. The ratc et pawl is arranged in aprotuberance 15 extending from the surface of the male member. A. socket16 is arranged in this protuberance andinthis socket the pawl 18islaced. The pawl has the stem 19 exten ing from it.

This stem extends into the' socket 20, the.

socket 2O opening into the socket 16. A. spring 22 is positioned betweenthe shoulder 21 and the end of the socket 16 and tends to crowd the pawloutwardly. A socket 23 is arranged on the upper face of the pawl and ascrew 24 extends into this socket and locks the pawl in the socket 16.The pawl is provided with a beveled surface 25 so that operating withthe beveled ratchet teeth, the members ma be readily turnedl to place,the beveled su aces operating onev upon the other during this movementand actuating the pawl. The pawl prevents, however, a return orloosening movement of the members by reason of the straight face of thepawl operating against the straight face of the ratchet teeth. Theprotuberance 15 has an over-hanging lip 26 which acts as a guard forpreventing the pawl from getting accidental thrusts. This is importantwhen used with fire hose when the uncoupling would be a serious matter.A slot 27 is made in the over-hangin lip through which an instrument mayIie Yextended for operating the pawl for unlocking the coupling. Thepawl as the end 28 extending into this slot for this purpose.

The cou ling is provided with a Spanner post 29 an a Spanner wrench 30is rovided with thel erforations 31 which is a apted to engage tlie post29. A finger 32 extends from thewrench and is so distanced from theperforation 31 and so shaped that when the wrench is placed on the ost29, the post extending through the perforations 31, the iinger 32 is inposition .to enter the slot27 against the end 28 of the pawl, so that bylongitudinal movement of the Spanner wrench, the pawl may be first movedto unlock'the coupling and by a rotating movement of the Wrench themembers may be uncoupled.

i refer to provide a guard lug 33 in front oi t e slot 28 ias a furthermeans of protectionl against accidental movement of the avv A p What iclaim as new is:

In a hose coupling mechanism the combination With the male and femalefittings having interlocking eams adapted to be interlocked by therelative axial and rotative movements of the members; of a lockingdevice comprising ratchet teeth on one of the members and a paWlarranged to move in an axial direction on the other of said members forholding the fittings in interlocked position; a Spanner wrench havingmeans for engaging one of said iittings and having devices thereon foractuating the pawl by direct en-,

gagement of the operative end of the awl and movement in an axialdirection Wh e in engagement with the fitting.

in testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
